This Festschrift volume is published in honor of Bernhard Steffen, Professor at the Technical University of Dortmund, on the occasion of his 60th birthday. His vision as well as his theoretical and practical work span the development and implementation of novel, specific algorithms, and the establishment of cross-community relationships with the effect to obtain simpler, yet more powerful solutions. He initiated many new lines of research through seminal papers that pioneered various fields, starting with the Concurrency Workbench, a model checking toolbox that significantly influenced the research and development of mode based high assurance systems worldwide. The contributions in this volume reflect the breadth and impact of his work. The introductory paper by the volume editors, the 23 full papers and two personal statements relate to Bernhard's research and life. This volume, the talks and the entire B-Day at ISoLA 2018 are a tribute to the first 30 years of Bernhard's passion, impact and vision for many facets of computer science in general and for formal methods in particular. Impact and vision include the many roles that formal methods-supported software development should play in education, in industry and in society.

This book constitutes the thoroughly refereed post-proceedings of the First International Workshop on Formal Modeling and Analysis of Timed Systems, FORMATS 2003, held in Marseille, France in September 2003.

The 19 revised full papers presented together with an invited paper and the abstracts of two invited talks were carefully selected from 36 submissions during two rounds of reviewing and improvement. All current aspects of formal method for modeling and analyzing timed systems are addressed; among the timed systems dealt with are timed automata, timed Petri nets, max-plus algebras, real-time systems, discrete time systems, timed languages, and real-time operating systems.

This book constitutes the refereed proceedings of the 14th International Conference on Computer Aided Verification, CAV 2002, held in Copenhagen, Denmark in July 2002. The 35 revised full papers presented together with five invited contributions and 11 tool presentations were carefully reviewed and selected from 94 submissions. The papers are organized in topical sections in symbolic model checking, abstraction/refinement and model checking, compositional/structural verification, timing analysis, SAT based methods, infinite state model checking, extended model checking, code verification, regular model checking and acceleration, and model reduction.

This book constitutes the refereed proceedings of the 12th International Conference on Concurrency Theory, CONCUR 2001, held in Aalborg, Denmark in August 2001.
The 32 revised full papers presented together with six invited contributions were carefully reviewed and selected from 78 submissions. The papers are organized in topical sections on mobility, probabilistic systems, model checking, process algebra, unfoldings and prefixes, logic and compositionality, and games.

This book constitutes the refereed proceedings of the 25th International Colloquium on Automata, Languages and Programming, ICALP'98, held in Aalborg, Denmark, in July 1998.
The 70 revised full papers presented together with eight invited contributions were carefully selected from a total of 182 submissions. The book is divided in topical sections on complexitiy, verification, data structures, concurrency, computational geometry, automata and temporal logic, algorithms, infinite state systems, semantics, approximation, thorem proving, formal languages, pi-calculus, automata and BSP, rewriting, networking and routing, zero-knowledge, quantum computing, etc..

This book presents 12 revised refereed papers selected as the best from 32 submissions for the First International Workshop on Tools and Algorithms for the Construction and Analysis of Systems, TACAS '95, held in Aarhus, Denmark, in May 1995.
The workshop brought together 46 researchers interested in the development and application of tools and algorithms for specification, verification, analysis, and construction of distributed systems. The papers included in the book are devoted to refinement-based and compositional verification, construction techniques, analysis and verification via theorem proving, process algebras, temporal and modal logics, techniques for real-time, hybrid and probabilistic systems, and value-passing systems.

This volume contains the proceedings of the third International Workshop on Computer Aided Verification, CAV '91, held in Aalborg, Denmark, July 1-4, 1991. The objective of this series of workshops is to bring together researchers and practitioners interested in the development and use of methods, tools and theories for automatic verification of (finite) state systems. The workshop provides a unique opportunity for comparing the numerous verification methods and associated verification tools, and the extent to which they may be utilized in application design. The emphasis is not only on new research results but also on the application of existing results to real verification problems. The papers in the volume areorganized into sections on equivalence checking, model checking, applications, tools for process algebras, the state explosion problem, symbolic model checking, verification and transformation techniques, higher order logic, partial order approaches, hardware verification, timed specification and verification, and automata.
